Special-shaped heating tubes are heating devices made of high-temperature-resistant stainless steel or quartz as the base material, internally filled with resistance wires and crystalline magnesium oxide powder, which transfer heat through the resistance wires generating heat when electrified. Their core features include:
Structure and Materials
?Metal Material?: Typically made of 304 stainless steel or 316L stainless steel, with embedded spiral resistance wires and an outer layer filled with crystalline magnesium oxide powder with good thermal conductivity, supporting dry firing conditions. ?
?Quartz Material?: Made of quartz tubes with integrated resistance heating elements, featuring efficient infrared radiation characteristics, capable of directly heating target objects in a vacuum environment. ?
Performance Characteristics
?High Efficiency and Energy Saving?: Metal materials have high thermal efficiency, while quartz materials can achieve up to 80% electrical energy conversion rate, with fast startup (reaching full power within 5 seconds). ?
Durability?: Average lifespan exceeds 5,000 hours, supporting high temperatures (up to 900°C) and rapid cooling. ?
?Flexible Application?: Supports customization of non-standard structures such as Z-type, W-type, and spiral shapes, suitable for liquid heating, mold temperature control, plastic processing, and other fields. ?
Main Applications
?Industrial Heating?: Used for heating oil, water, chemical media, as well as temperature control for hot press molds. ??Special Processing?: Suitable for equipment such as coating baking tunnels, PET bottle blowing machines, and photovoltaic sintering furnaces.
